the windows 7 with updates seems to support up to 11.1
Is this real ?, can i not install the DX11,2 SDK on windows 7 ?
Correct, you cannot install DX11.2 on Windows 7.
As was written above, DirectX has been tied to the OS version since 2006. The last OS to have separate editions of DirectX was Windows XP.
DirectX 10 was Windows Vista. Portions of DX11 were backported in Service Pack 2 after consumer and developer outcry.
DirectX 11 was Windows 7. Portions of DX11.1 were backported to Windows 7 in the service pack, but there was significant missing functionality.
DirectX 11.1 was Windows 8.
DirectX 11.2 was Windows 8.1.
DirectX 11.3 was Windows 10, as the final update to the DX11 series.
DirectX 12 is Windows 10, and there are three versions so far. There was the initial version with SDK 10240 (initial launch), SDK 15063 ("Creators Update", also called 1703), and SDK 17763 ("October 2018 Update"). You only get the functionality if you update Windows 10 to that version.

Is there not a problem that i accidently install the to new version for my system ?
No, unless you accidentally move from Windows 7 to Windows 8.1. If you want DX11.2, you must migrate the system to Windows 8.1. If you move to Windows 10 you get DX11.3.

I still have visual studio 2005 the profesional edition with box and discs, is that a problem ?
I think the last version of the Windows SDK that work SDK v7.1 from 2010. After that, VS2005 could be manually configured to point to the newer compiler and newer libraries and headers.
